1. The problem statement, all variables and given/known data An infinite line of charge is along the entire x axis has a constant value for λ. A hemisphere is centered at the origin and has a base circle of radius a. What is the electric flux throught the hemisphere 2. Relevant equations Flux = Q enclosed / ε 3. The attempt at a solution Q enclosed must be λ* (2a) .. Thus, the answer should be 2λa/ε. Is this right or should we half it.. I mean would this be the same answer if the hemisphere was a full sphere. Thanks for helping!
